Architect, they need to know trigonometry functions, among others they utilize to find the size of unknowns parts of shapes.
Surveyors, carpenters.
Trig is not restricted to angles, it has huge applications in waves, and occurs frequently as solutions to certain common differential equations. It is needed by any job that uses math. Thus, all engineers need trig, and it would be beneficial to any person who pursues science.

Math is an important part of your life. Most jobs require you to no math and be able to calculate well.
Not many jobs don't involve math. Most jobs require you to know basic math skills, such as arithmetic and perhaps some basic algebra and geometry. If you want to become an engineer or scientist or something, you will probably need much more math knowledge than that. I assume that most writing jobs don't require math skills (author, blahblahblah).
Plane trigonometry is trigonometry carried out in (on) a plane. This could be contrasted with spherical trigonometry, which is trigonometry carried out on the surface of a sphere. Certainly there are some other more complex forms of trig.
Trigonometry
The way you do trigonometry is by working with triangles. Trigonometry is a math class that is taught in high school and usually followers algebra and geometry.
